Interference of unburned and activated carbon in fly ash with air-entraining admixtures (AEA’s) in fresh concrete mixtures is a major concern in the concrete industry. Therefore, a rapid and accurate measurement of adsorption capacity of fly ash is of great interest to this industry. In this project, a new method is suggested, which can qualitatively and quantitatively measure different surfact ...

Paralytic shellfish poisoning (PSP) due to consumption of contaminated shellfish is an increasing problem is the coastal waters of the United States, particularly in New England and the Pacific Ocean. The symptoms of PSP include vomiting, diarrhea, shortness of breath, confusion, and loss of coordination in both marine animals and humans. In severe cases, PSP toxins can cause respiratory failure a ...

In Phase I, a novel porous electrode was designed to demonstrate a rapid, simple assay for the detection of domoic acid in marine samples. During Phase II, methods to manufacture porous electrodes will be improved to enable high volume production of low-cost biosensors that can be connected to a potentiostat. These biosensors will be incorporated into a portable test kit for the quantitation of do ...

In Phase II, Propagation Research Associates, Inc., (PRA) proposes to complete the development of a real-time nowcast of ionospheric scintillation impacts on GPS users. Continuing its partnership with NASA’s Jet Propulsion Laboratory, PRA will implement real-time production of a map of ionospheric scintillation parameters over the United States using real-time data streamed from the National Geo ...

Not Available ORBITEC proposes the development of a Lunar Ice Simulator (LIS). The objective of the research is to create a system that can simulate the physical structure of the lunar ice/dust mixtures to test and demonstrate mechanisms for the mining and processing o

THERE IS A NEED FOR A RAPID, NON-DESTRUCTIVE METHOD TO TEST FOR PROPER STEEL PLACEMENT IN PORTLAND CEMENT PAVEMENTS. ISTHE GOAL OF THIS PROPOSED PROGRAM TO DEMONSTRATE THE FEASIBILITY OF USING SHORT-PULSE, GROUND-PENETRATING RADAR AS A MEANS OF RAPID STEEL LOCATION IN CONCRETE PAVEMENT. A GENERAL BACKGROUND IN GROUND-PENETRATING RADAR THEORY IS PRESENTED. LABORATORY AND FIELD MEASUREMENTS USING A ...

THE PROPOSED PHASE I EFFORT WOULD EVALUATE THE FEASIBILITY OF DEVELOPING A NOVEL FIBEROPTIC VISION SYSTEM FOR LARGE MOTOR VEHICLES. A NEW, BETTER MEANS OF SIDE AND REAR VISIONIS NEEDED FOR HEAVY TRUCKS AND BUSES. THE DRIVERS OF THESE VEHICLES HAVE DIFFICULTY SEEING OTHER VEHICLES IN TRAFFIC LANES TO THEIR IMMEDIATE RIGHT. WHEN THE CAB AND TRAILER OFTHE HEAVY TRUCK ARE AT AN ANGLED POSITION OR A HE ...
